Definition
Regulates biological clock/circadian rhythms
Term

Term
Cortisol (glucocorticoids) - Effects
Definition
"Help regulate metabolism by breaking down proteins (bad) and lipids as energy. Nutrients available for ATP. Vasoconstriction (increase BP). Anti-Inflamatory; reduce histamine from mast, less capillary permability."
Term
Androgens (Small Amount Only!!) - Effects
Definition
"Sex drive in females, converted to estrogen in postmenopausal femals"
Term
Insulin - Effects
Definition
"Acceleration of glucose uptake & glucose utilization, glycogen formation"
Term

Definition
"Stimulates glycogenolysis (break down glycogen), fat catabolism (triglycerides) and absorption of amino acids for gluconeogenesis (glucose production by liver)"
Term
Somatostatin - Effects
Definition
Supresses release of glucagon and insulin by islet cells and slows rate of food absorption and enzyme secretion by digestive tract.
Term
Epinephrine & Norepinephrine - Effects
Definition
"Longer lasting, increase BP & heart rate, increase blood flow to skeletal muscle, increase air flow, decrease digestion & urine, increase glucose available."
Term
Progesterone - Effects
Definition
"Development of female reproduction system, menstrual cycle/sustain pregnancy & prepare mammary glands for lactation. Secrete inhibin & supress FSH"
Term
Inhibin - Effects
Definition
Inhibits secretion of follicle stimulating hormone and luteinizing hormone
Term
